Description

Technical Field

[0002] Cold chain logistics cold storage, referred to as logistics cold storage, is a kind of building equipment specially used for storing food or refrigerated goods. The door of logistics cold storage mainly uses the sliding door mechanism to ensure the closure of the entire logistics cold storage. At the same time, in order to avoid serious loss of cold storage due to frequent entry and exit during the day, the sliding door mechanism is generally equipped with air curtain machines and return cages to reduce the loss of cold air.

[0003] However, when the warehouse door is high, the air curtain machine cannot block the alternation of air inside and outside the warehouse door, which will cause a large amount of cold air to be lost, and dust or foreign objects are easily accumulated inside the air curtain machine, which is not very friendly to environmental hygiene. At the same time, the air curtain machine also has problems such as high noise and high energy consumption. The return cage room exists in the form of an aisle and cannot store goods. Its excessive length will increase the aisle area while reducing the storage area. The return cage room will also affect the operator's route of action and affect work efficiency.

[0016] S1: Select a test site, transform the terrain of the test site, install corresponding refrigeration equipment, and assemble and deploy the cold storage channel combination doors that need to be tested and compared;

[0017] The specific steps are: setting up the test environment, which includes test environment requirements, test location and test tools;

[0057] Two connecting frames 10 are fixedly installed on the top of the heat-insulating door panel 9 , and connecting plates 11 are fixedly installed on one side of the top of the two connecting frames 10 . The two connecting plates 11 are fixedly connected to the synchronous belt 7 .

[0058] Through the above technical solution, the connecting frame 10 and the connecting plate 11 are used as connecting parts between the thermal insulation door panel 9 and the synchronous belt 7, so that the synchronous belt 7 can drive the thermal insulation door panel 9 to move left and right.

[0063] Both sides of the two heat-insulating door panels 9 are provided with abutment wheels 24 , and both sides of the heat-insulating door panels 9 are fixedly mounted with two parallel rail grooves 25 , and the rollers on the two abutment wheels 24 are in contact with the two parallel rail grooves 25 respectively.

[0064] Through the above technical solution, the wheel 24 cooperates with the parallel track groove 25 to limit the lower half of the thermal insulation door panel 9, so that the thermal insulation door panel 9 can operate stably without affecting the thermal insulation door panel 9.

[0065] Two insulation baffles are fixedly installed at the bottom of the insulation door panel 9, and an L-shaped insulation sealing strip 26 is fixedly installed on one side of the insulation door panel 9.

[0066] Through the above technical scheme, the insulation baffle is mainly used to cover the gap at the bottom of the insulation door panel 9, and the L-shaped insulation sealing strip 26 is mainly used to cover the gap between the insulation door panel 9 and the cold storage partition panel 1, so as to ensure the sealing of the insulation door panel 9.

[0067] An L-shaped fixing strip 19 is fixedly installed on one side of the cold storage partition board 1, and two sliding shafts 20 are slidably installed on the L-shaped fixing strip 19. The same connecting strip 21 is fixedly installed on one end of the two sliding shafts 20, and the same abutment plate 22 is fixedly installed on the other end of the two sliding shafts 20. Springs 23 are slidably sleeved on the two sliding shafts 20, and the two ends of the spring 23 are respectively in contact with the L-shaped fixing strip 19 and the abutment plate 22.

[0068] Through the above technical solution, the L-shaped fixing strip 19 cooperates with the upper sliding shaft 20, the connecting strip 21 and the abutment plate 22 to form a buffer mechanism, so that the thermal insulation door panel 9 is less impacted when closing.

[0069] The bottom end of the abutment plate 22 is provided with a through hole, and the cleaning roller 17 is adapted to the through hole.

[0070] Through the above technical solution, the opening ensures that the cleaning roller 17 will not restrict or interfere with the closing between the thermal insulation door panel 9 and the abutment panel 22 .

[0071] A long sliding opening 37 is provided on one side of the two rectangular cover shells 28 that are close to each other, and two connecting buckles 36 respectively penetrate the corresponding long sliding openings 37 and are slidably connected to the corresponding long sliding openings 37. Two limit strips 39 are fixedly installed on one side of the two rectangular cover shells 28.

The two limit strips 39 can cooperate to form a slide rail, thereby limiting the thermal insulation fast rolling door 34, thereby improving the stability of the thermal insulation fast rolling door 34 without affecting the normal winding of the thermal insulation fast rolling door 34. The "concave" shaped magnetic gate pad 38 is installed on the ground, which allows the rectangular gate box 35 at the bottom of the thermal insulation fast rolling door 34 to be stuck in the "concave" shaped magnetic gate pad 38 when the thermal insulation fast rolling door 34 is closed, thereby ensuring the overall sealing.

[0073] The implementation principle of a cold storage channel combination door suitable for cold chain logistics in the embodiment of the present application is:

[0074] The first step: when the cold storage is frequently entered and exited, the sliding door mechanism can be opened in advance, so that the two heat preservation door panels 9 are in the open state for a long time, and only the fast rolling door mechanism is in the closed state to prevent the loss of cold air in the cold storage. When closing the sliding door, the first motor 3 is started, and the first motor 3 drives the first bevel gear 4 to rotate through the output shaft. The first bevel gear 4 drives the corresponding synchronous wheel 5 to rotate through the second bevel gear 6, and the corresponding synchronous wheel 5 drives the synchronous belt 7 to move. When the synchronous belt 7 moves, it drives the heat preservation door panel 9 to move until the heat preservation door panel 9 contacts the abutment plate 22, and When the two are in contact, the abutment plate 22 will squeeze the spring 23 after being hit by the thermal insulation door panel 9, so as to buffer the impact when the two are in contact. At the same time, when the thermal insulation door panel 9 is moving, the two pulleys 15 will roll on the ground, and the corresponding pulley 15 will drive the third bevel gear 16 to rotate during the rolling process. The third bevel gear 16 drives the cleaning roller 17 to rotate through the fourth bevel gear 18. The cleaning roller 17 can automatically sweep away gravel or other scattered small debris on the moving path of the thermal insulation door panel 9 by rotating, so as to avoid affecting the normal closing of the thermal insulation door panel 9.

[0075] The second step: when the staff approaches the fast rolling door mechanism, the radar sensor on the fast rolling door mechanism starts the second motor 29 after receiving the induction, and the second motor 29 drives the winding roller 30 and the two first synchronous wheels 31 to rotate through the output shaft. The winding roller 30 starts to reel the fast rolling door 34 by rotating. At the same time, the first synchronous wheel 31 drives the second synchronous wheel 32 to rotate through the synchronous belt 33. The synchronous belt 33 will also drive the rectangular gate box 35 to rise through the connecting buckle 36 during transportation, thereby realizing the rapid opening of the thermal insulation fast rolling door 34, thereby ensuring the normal entry and exit of the staff and reducing the loss rate of cold air in the cold storage.

[0076] like Figures 14 to 27As shown, the present invention also provides a testing method for a cold storage channel combination door suitable for cold chain logistics, comprising the following steps:

[0077] S1: Select a test site, transform the terrain of the test site, install corresponding refrigeration equipment, and assemble and deploy the cold storage channel combination doors that need to be tested and compared;

[0078] The specific steps are: setting up the test environment, which includes test environment requirements, test location and test tools;

[0079] The test environment is required to be a low temperature warehouse and a high temperature warehouse, with the temperatures set to -18℃ freezer and 7℃ cold storage, -18℃ freezer and room temperature hall respectively;

[0080] Test location: Scheme 1, Door 1 of Warehouse 1, the temperature setting is: -18℃ freezer and 7℃ cold storage, the temperature difference is 25℃; Scheme 2, Door 2 of Warehouse 1, the temperature setting is: -18℃ freezer and 7℃ cold storage, the temperature difference is 25℃; Scheme 3, Warehouse 2 of Warehouse 5, the temperature setting is: -18℃ freezer and 16℃ hall, the temperature difference is 34℃;

[0081] The test tools include a temperature imager, an electronic thermometer and a ruler. The model of the temperature imager is i400+, and the model of the electronic thermometer is GSP-6.

[0082] S2: Then conduct comparative tests on the air tightness, thermal insulation and energy-saving effects of the cold storage channel combination doors one by one;

[0083] The specific steps are: determine the test plan, which includes test scheme, product parameters, door curtain insulation performance test, door opening and closing test, fast rolling door reset test, sealing comparison, door comparison before and after installation, graphic comparison before and after installation of fast rolling door, and calculation method for use and deactivation of fast rolling door;

[0084] Test plan: After the floor renovation, three types of fast-rolling doors were installed for usage comparison and performance analysis, and the installation position, air tightness, thermal insulation, and energy-saving effects were compared;

[0085] The specific test schemes include Fig.13 As shown in the figure, three different combinations are used to test the performance of three fast rolling door products. All the fast rolling doors in the three solutions are installed on the low temperature side.

[0086] Plan 1 uses Xinhuafa brand rolling shutter doors, and Plan 2 uses Jieman brand rolling shutter doors;

[0087] Product parameters are as follows Fig.14 and Fig.15As shown in the above data, the door opening and closing time is controlled within 10 seconds; thermal conductivity is a parameter that reflects the thermal insulation performance. The lower the thermal conductivity, the better the thermal insulation performance. The combined door body is better than Scheme 2 and Scheme 1; the power-off manual opening and closing function can only be realized in Scheme 1; the derailment self-reset function is available in Scheme 1 and the combined door body, but not in Scheme 2;

[0088] Among them, the specific data of the door curtain insulation performance test are as follows Fig.16 , Fig.17 and Fig.18 As shown, it can be seen from the comparison of the above two groups that the thermal insulation performance of the door curtain of scheme three is better than that of scheme one and scheme two;

[0089] Among them, the door opening and closing test and self-reset function test time and data have been tested and obtained;

[0090] Containment comparison: Fig.19 , Fig. 20 As shown, the above comparison shows that Scheme 1 and Scheme 3 are better than Scheme 2 in terms of airtightness;

[0091] Graphic comparison before and after the installation of the fast rolling door, the data comes from the Tianshang platform: Fig.21 and Fig. 22 As shown above; through the comparison of the above data, when the ambient temperature before the installation of the fast rolling door is lower than the ambient temperature after installation, the warehouse temperature compliance rate is increased by 41% and the refrigeration time is reduced by 5%;

[0092] The calculation of the use and deactivation of the fast rolling door is based on the data from the Tianshang platform. Fig.23 As shown; the above table is the usage and discontinuation data. Use the above data to calculate the help of fast rolling doors to cold storage. The net area of ​​5 warehouses and 2 warehouses is about 682 square meters; the cooling capacity requires 51kw. According to the Bitzer selection software, it is necessary to use a 30P screw compressor with an electric power of 23.5kw / h, and each kw / h is calculated at 0.8 yuan; on average, using fast rolling doors requires 5.58 more cooling hours per day than not using fast rolling doors. The extra power consumption = 5.58h*23.5kw / h=131.13kw / h, the extra electricity cost = 131.13kw / h*0.8 yuan=104.9 yuan, and the extra electricity cost per year = 104.9 yuan*365 days=38288.5 yuan. Through the above calculation, it can be seen that a 680㎡ warehouse can save about 38,000 yuan in electricity bills, which is greater than the price of a fast rolling door, and the temperature compliance rate is higher than the current 13%. Through the above calculation, fast rolling doors play an outstanding role in energy saving and temperature compliance rate.

[0093] S3: The test results obtained by comparison can alleviate the severe icing around the cold storage door, the cold storage door running cold, reduce the door deicing work and improve the safety factor, as well as save energy and reduce emissions.

[0094] The price is for fast rolling doors within 9㎡, including ticket, transportation and installation. Through the comparison of the above important parameters, Plan 1 has obvious advantages over Anton in terms of anti-collision performance and airtightness performance; Anton has a greater advantage in terms of thermal insulation performance; Plan 1 has a greater advantage in terms of price;

[0095] It solves the technical problems of frequent operation of traditional warehouse doors, severe ice formation at the cold storage door, and severe cold leakage from the cold door.

[0096] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
